Then I re-stored the QVD in Sense to convert in then new QVC. When I load one qvc only I observe performance gains in reload time ( (about twice faster) but when I tried to load *.qvc, Qlik Sense seems to struggle, reload time are much more slower from the second QVD loaded and finally get completely stuck after trying to concatenate the third QVD (RAM seems to reach limits , RAM usage curve is really unexpected.

I can provide QVDq and/or QVF if it can help. (Same behaviour in Sense 1.1)

Re: Sense Data load : Troubles when concatening QVC

Hi Michael - I ran this by a few people - and we are trying to understand what you mean by QVC. I am not aware of a .qvc file format. I know at one time, .qvc was referred to as this new structure, but never saw the .qvc extension. Do you mean the new format that Qlik Sense stores the data in, which is still technically a QVD file, or something else?

Can you attach your .qvf file (Qlik Sense App) or script code- so we can take a look?

Re: Sense Data load : Troubles when concatening QVC

Hey Bill,

Please find attached log files. They do not tell a lot about what's happening. See that first QVD load is very fast ~30 sec, then second one is 4 minutes ?? then I stop at the third one when memory is 100%, system freezes.
